Both quotes are for Simonton 5050 windows installed in a concrete block home.
Eight windows are 110UI, three are 130UI, two are 101UI, one is 93UI, and one is 73UI.
The eye brows are 76 and 71UI respectively. One picture window is 96UI.

Its unfair for us to comment on price unless its aggregiously high or low. There are far too many variables when determining price for us to pull a figure out of the sky or comment on someones estimate when neither of us have evaluated the job in person.
Some of the variables include the quality of the window itself, the experience of the installers, the install material being used, the complexity of the job, size of the company overhead, size of the job, cost of insurance, region, distance traveled ,and about a million other things.
